Field Description
Peer LDP Ident LDP (or TDP) identifier of the neighbor (peer) for this session.
Local LDP Ident LDP (or TDP) identifier for the local label switch router (LSR) for this
s
ession.
TCP connection TCP connection used to support the LDP session, shown in the following
fo
rmat:
• peer IP address.peer port
• local IP address.local port
Password Indicates if password protection is being used. Password status is as follows:
• Required or not required—Indicates whether password configuration is
required.
• Neighbor, none, option #, or fallback—Indicates the password source
when the password was configured.
• In use (current) or stale (previous)—Indicates the current LDP session
password usage status.
State State of the LDP session. Generally, this is Oper (operational), but transient
i
s another possible state.
Msgs sent/rcvd Number of LDP messages sent to and received from the session peer. The
c
ount includes the transmission and receipt of periodic keepalive messages,
which are required for maintenance of the LDP session.
Downstream on demand Indicates that the Downstream on Demand method of label distribution is
b
eing used for this LDP session. When the Downstream on Demand method
is used, an LSR advertises its locally assigned (incoming) labels to its LDP
peer only when the peer requests them.
Downstream Indicates that the downstream method of label distribution is being used for
thi
s LDP session. When the downstream method is used, an LSR advertises
all of its locally assigned (incoming) labels to its LDP peer (subject to any
configured access list restrictions).
Up time Length of time (in hours, minutes, seconds) the LDP session has existed.
Graceful Restart
en
abled
Indicates whether the LDP session has Graceful Restart enabled.
Peer reconnect time The length of time, in milliseconds (ms), the peer router waits for a router to
r
econnect.
LDP discovery sources Sources of LDP discovery activity that led to the establishment of this LDP
s
ession.
